The Omo Valley is located in the south-western corner of Ethiopia and shares its borders with Kenya and Sudan. Many anthropologists consider it to be the birthplace of mankind.

Several ethnic groups inhabit the valley, living in surroundings that seem nearly unchanged from the Bronze Age. The Hamars, the largest tribe in the Eastern area, number 15,000 strong, while their neighbors, the Karos, are less than 600.

The presence of modern civilization is slowly stealing its way into this far-flung corner of Ethiopia, due to the arrival of evangelistic visitors and tourist groups. The menacing proliferation of Kalashnikov rifles worsens the scenario in this beautiful valley, where fighting amongst tribes is often frequent.
